HOSE COUPLING OR CONNECTOR.

Specification of Letters Patent.

Patented April 1'7, 1906.

Application filed September 25, 1905. Serial No. 279,876.

To all whmn it Duty concern.-

Be it known that we, J OHN I. TREDTIN and FREDERICK H. GROSBERNT,citizens of the United States, residing at Dayton, in the I same,reference being had to the accompanying drawings, and to the figures ofreference marked thereon, which form a part of this specification.

This invention relates to improvements in couplings or connectors forhose and faucets.

The object of the invention is to provide a simple and effectiveconnector for readily connecting or coupling hose to faucets, such meansbeing easily manipulated to effect a most rigid connection.

The connector is entirely free from screws or other parts liable to belost or misplaced.

The parts of the connector besides being free from screws arepermanently connected with the hose, on the one hand, and the faucet, onthe other.

Preceding a detail description of the invention reference is made to theaccompanying drawings, of which Figure 1 is a side elevation of afaucet, showing our improved connector in position thereon. Fig. 2 is aview on the line y y of Fig. 1 looking in the direction of the arrow.Fig. 3 is a view looking in the direction of the arrow (1 in Fig. 1.Fig. 4 is a sectional view on the line :0 a: of Fig. 2. Fig. 5 is adetached view of the hose-tube, the same containing modifications inconstruction which render its use without the common form of hosetube.

In a detail description of the invention similar reference charactersindicate corresponding parts.

1 designates the usual faucet, having a connection with a service-pipe 2through means of a common form of union 3. The neck or discharge end ofthe faucet is provided, as usual, vdth exterior screw-threads 4.Engaging these screw-threads4 is a ring 5, which screws against theflange on the discharge end of the faucet; From opposite sides of thisring 5 project trunnions 6, and from the lowergorjrearsidelofsaidgingfaffplate 7 laterally projects and serves as a stop tofacilitate the operations of coupling.

8 designates a nipple or coupling-piece which has a screw-threadedextension 9, that engages the hose-tube 10 by being screwed into thesame. Opposite sides of the nipple 8 are flat, as at 11, and shoulders17 are thus formed on said nipple, which slightly taper from one end tothe other of said shoulders. The object and purpose of these taperedshoulders is to form a wedge-like engagement with a coupling-frame to bepresentl described. The screw-threaded end 4 of the faucet projects intothe nipple 8 and engages a gasket 19 within said nipple; but the saidscrew-threaded end 4, it will be understood, has no screw-threadedconnection with the nipple 8. On the contrary, it is forced in rigidcontact with the gasket 19 by means presently described, consisting ofthe frame hereinbefore referred to. This means consists of acouplingframe consisting of lower and upper arms 13 13 and 16 16, whichare joined by an integral cross-plate 14 and in which is provided anoblong rectangular opening 15, that receives the nipple 8. The upperarms 16 16 engage the trunnions 6 on the ring 5, while the lower arms 1313 engage the opposite surface 11 of the nipple, and the shoulders 17,which, as before stated, are tapered.

The upper sides of the arms 13 13, it will be seen from Fig. 1, slightlytaper in a direction opposite the taper of the shoulders 17 and thus awedge-like engagement occurs between these parts when the coupling-frameis forced in contact with the nipple. The coupling-frame is connected byhand, suflicient force being thus applied to rigidly draw the gasket 19in contact with the end of the faucet, as shown in Fig. 4..

It will be seen that the upper arms 16 16 of the frame engage thetrunnions 6 on the ring 5. The engaging surfaces of these parts 16 16may also taper similar to the lower arms 13 13, and it will be clearlyunderstood that in pressing the coupling-frame in engagement with thetrunnions 6 and the shoulders 17 the parts become wedged together in amost rigid manner.

In Fig. 1 a common form of hose-tube 10 is shown as a means forconnecting the hose 18 with the faucet, and this figure illustrates thatour improved connector may be utilized for connecting any hose havingthis common form of hose-tube 10 with the faucet. In this case thenipple Sis screwed into the hosetube 10 and is allowed to so remain, andthe ring 5 is allowed to remain permanently con nected with the faucet,so that all that is necessary in making the connection is to bring thenipple S in contact with the end of the faucet and apply thecoupling-frame in a manner hereinbefore described. In making theconnection the part 7 of the ring 5 acts as a stop to center the nipple8 and the end. of the faucet.

Fig. 5 shows a form of hose-tube 10 which combines in one piece thenipple 8, so that the common form of hose-tube shown in Fig. 1 may bedispensed with, and the nipple 8 serves the purpose of a connectiondirectly with the hose 18 and directly with the end of the faucet. Theconstruction of the nipple as shown in Fig. 5 is otherwise the same,having the flat sides 11 and the shoulders 17, and it is furtherprovided with the gasket 19, against which the end of the faucetengages. The coupling-frame is not detachable from the nipple 8 after itis placed in connection therewith. It will therefore be seen that thereis no danger of said coupling-frame becoming lost or misplaced. hen thesaid frame is placed on the nipple 8, the rear ends of the arms 13 13are bent inwardly, as at 20, to decrease the area of the entrance to thespace 15, which is occupied by the nipple, and which nipple is therebyprevented from becoming disconnected or detached from saidcoupling-frame.

Having described our invention, we claim- 1. In a hose-connector, thecombination with a faucet, of a nipple having two tapering shouldersdisposed on opposite sides of said nipple, a coupling-frame havingparallel arms with inner tapering sides, two of said arms engaging theshoulders on the nipple, and means on opposite sides of the faucetengaged by the tapering surfaces of the other of said parallel arms, andwhereby the nipple is clamped to the faucet, substantially as specified.V

2. In a connector, a ring attachable to the discharge end of a faucet,said ring having trunnions projected from opposite sides, a nippleattachable to the hose, said nipple having shoulders on opposite sides,and a coupling-frame engaging said shoulders, and said trunnions on saidring, whereby the nipple is forced in rigid contact with the end of thefaucet, substantially as set forth.

3. In a connector, a trunnion member attachable to the mouth of thefaucet, a nipple attachable to the hose, said nipple having on oppositesides flat surfaces terminating in tapering shoulders, and an open framehaving four projecting parts which are adapted to engage respectively,the trunnions on said trunion member, and the shoulders on said nipple,and whereby wedge-like means are provided for forcing the nipple rigidlyagainst thei end of the faucet, substantially as specifie In testimonywhereof we affix our signatures in presence of two witnesses.
